The examination identified a complex disease process involving severe chronic inflammation, stomach ulceration, and persistent internal bleeding. These findings provide clarity on the medical challenges she faced during her final weeks of life. ## Impact of Avian Influenza A critical factor in Jackie's health decline was a diagnosis of Highly Pathogenic Avian Influenza, commonly known as bird flu. This viral infection was identified as the primary driver behind her severe stomach ulceration. Raptors, including eagles and hawks, remain highly susceptible to this virus, which complicates rehabilitation efforts for injured wild birds. ## Timeline of Final Decline Jackie was admitted to the center in July following an altercation with other eagles near Dana Point Park. Her condition deteriorated significantly throughout early August, characterized by severe anemia and unstable vital signs. Despite intensive veterinary care, she passed away on August 10, marking the end of her well-documented life in Big Bear. ## Clinical Complications and Findings The pathology report did not identify a single cause of death, but rather a combination of systemic failures. Beyond the influenza, pathologists found blood clots in her wing and kidney, alongside liver and lung abnormalities. Her packed cell volume reached critically low levels, reflecting the severity of her internal health struggles before death. ## Collaborative Veterinary Effort The necropsy was performed by specialists at the San Diego Zoo Wildlife Alliance. The Ojai Raptor Center emphasized that the process involved numerous veterinary experts, laboratories, and wildlife agencies. This collaborative approach was essential to understanding the specific illness and ensuring that Jackie received the best possible care during her final hospitalization. ## Legacy of Big Bear Eagles Jackie became a global icon through live cameras managed by Friends of Big Bear Valley. Her story, from her 2012 birth to her successful nesting seasons with partner Shadow, captivated millions. The organization plans to share further reflections once their team has fully processed the detailed findings contained within the official veterinary medical journal. ## Conservation and Future Research California Department of Fish and Wildlife Director Meghan Hertel noted that Jackie’s case offers vital insights for wildlife management. Understanding these test results helps inform future care and treatment protocols for other eagles. The data gathered serves as a learning opportunity for wildlife agencies working to protect iconic species across the region. ## Supporting Ongoing Recovery Efforts To honor Jackie's memory, Friends of Big Bear Valley continues to accept donations for local conservation initiatives. Additionally, the Ojai Raptor Center maintains a Bald Eagle Recovery Campaign to support their ongoing rehabilitation work. These contributions help sustain the infrastructure required to provide medical intervention for injured raptors in Southern California. ## Sources covering this story - https://www.popsci.com/environment/jackie-eagle-cause-of-death/ — --- _Summary written by Brifing from the original reporting.
